Be. it known that I, R.. DAnnl'Nc, a-c1t1zenio`f theUlted States, residingl at Indiana oli's, in the county of Marion and '-5 State o Indiana,'have invented' a new and .s pseful/Ozonator, 1of which 'the following is :l t is the object of my invention to provide an electrically opera dbozonator which prolu' duce's ozone *withv7 ,leor no contamination by oxids of ni'trgen, requires but little electrical .energy for it'sfoperation,4v requires but low 'tension conductors leading to theI ozone' roducin apparatus is free from danger, is

P ger all the. iisual Vcomniercial lighting' vo tages and either alternating or'di- E rect current, and is simple 4and inexpensive in construction 'a'well as in operation.

Ozone' is produced when a practically free from oxids of nitro en. Ac-

i :produce upthis' stress. very economically and'jsafely ,byTesla currents.; to .this end Iprvlde an duction co11 "having a primary winding ,and an V'openfci rcuited secondary'-winding 89. the lattelr preferablyhalvingl one` end nected to the former andhevtwo windings being located one inside' and 'one outsidefof ra tube of insulating material, and'connect theprimary winding infseries'with .a con- 35 densenacross thespark gap of a-vibrator in' series with -an inducta'nce across-a supplyv line. VThe tubeof insulating" material-1s so :mounted that there may be a `circulation of'air'wver atleast one winding-'on 1t.l 'and Q 245 is preferably placed with its axis 'vertical so lthat this circulation 4will .take place ,automatically through the tube upon the .production of ozone." The 'conductorsleadlngto the primary winding on the tube .carry ow The vaccornpanylng 'drawing illnstratesa.

hrough an ozonator embodying my mvenp'n, the electrical connections bems'h "j lnf'th-garifangement shown, a' casing 'is sciently "20 high electrical. stress i's set up in air, 'as for instance when-gcorona or glow appears; and

` .if 'violent' .sparking is avoided this -ozone isv center onel'ofwhich'is aniriductance"11,.a v v vibrator v12, and a"condenser 13, and in the. two outer o nes of which are the ozone-prob' ducmg devices. `The inductance. 11 servesi.

On' the bridge 16' are. mounted two binding postsl'? and 18', which may be connected to the two 'sides of tliefsupply circuit' 19 r' ectively, the bindff 7o mgpos't 1T being in ectrical connection. with the brldge 16 andthe binding post-18 'belng msulated from such bridge but con-- nected b`ya w1re 20 to one side of the in-y duct'ance 11, the other'jside of .sad'induc-- 7 6.

tance 1 1 being connected bya 'wire 21 to the v1brator'12 and to one side ofthe condenser 13. The circuit is thus from lone side of the supply line 19, through thebindng post 17, the bridge 16the adjustingscrew 80 I' 15, the vibratorl2, the wire 21,'the in'duc-- tance 11,the wlre 20, 'and the binding post 1 8. to the other side ofthe supply line.

'one on the insideand one onithe outside of the tube. Conveniently. the primary wind- 99'( ing is 'onthe inside of the tube andthe s'econdary vvfindingon the 'outside thereof. 'as sh'own. The' primary winding26 conven ientlvconsists of a Yfew turns .of corrugated metallic strip, the corrugations being most "52 Y' plainlyshown in Fig "2, andthe secondary I winding consists of a comparatively large number of turns `of-insulatedw1re wound onthe outside' of thetube25,and-shellaeked I to h o'ld themin` place. This .ozonemoduc- A1011i ing device :may be located wherever' desired, v but ira the selfcontained oz'bnator here 1ll`us` l\trated there is :one ozone-'p'roducing device .in each end compartment ofthe casing 10. A

Oneend ofthe primary winding '26 'of eachl 10e. i

ozone'.-1aroduc1n,z,l '.'device4 is' connected by a wire '28 tothe bridge 16. andthe other c nd "is connected by' a wire' 29 tothe opposltesxde. of thecondenser'l' ,from that' to .whwch the The 'ozone-producing'device in its simple v the primary and secondary windings being 21is connected. The crcuit'of'thesec- 110 form, comprises a1 tube 25 of insulatingma-j l ary winding 27 from that toy wliichthefwire i 30 is connected. Conveniently this connection is by a Wire 36 connectln` the up er ends of the two' secondary windings. hef' lower end ofthe secondary winding 36 is. left unconnected, or if there is no such secondary winding 36 the ulpper end of the secondary winding 27 is eft unconnected. The top 40 and the bottom fil of thev casing 10 above and below the tubes'25 and 35 are perforated to allow the Apassage o fair through su'clttubes. In operation, the magnetic action'of the inductance 11 causes the vibration`o the vibrator 12 and the alternate-making and breaking of the main circuit in the usiial manner. 'For eachbreak of .the circuit,-

there is a rapid oscillating discharge from the condenser through the primary windings 26 in parallel and the s'parlrgap be-Y tween the vibrator 12 'and its a ju'stiiig screw. By properly proportioning the inductance, the primary windings, and the condenser, the path of this-discharge maybe made resonant but exact resonance,- thou h desirable, is not at all necessary. This rapid' oscillating dischargp through the rimary. windings sets' up a igh frequency, igh pos tential lectrification of the secondary windings. The electrical stresses between the primary' windings 26 and the secondary windings 27, and between the secondary windings 2 7 and the secondary windings 36. produce discharges-which .ozonize and thus purify the air within-and near thesurfaces 25 and 35. This action is particularly noticeable, in the construction shown', ai'ljacent` those portions of winding 26^which are close to, but slightly separated from, the inner surface of tube 25, and with the anis 'of the tubes vertical there is a rapid circulation of air through the tubes.
